Trip Report: Río Orinoco (Amazonas State), Venezuela 17 th - 22 nd December 2006 (David Southall) Wire-tailed Manakins This report captures highlights from a trip that I made to Amazonas State at the invitation of David Ascanio and the Phelps Ornithological Collection. The objectives of the trip were to: 1) Rediscover the Orinoco Softtail (known only from one very specific site at Capuana along the Río Orinoco) - gathering data on its abundance, habitat, morphology, calls etc; 2) Carry out a rapid assessment of the various species encountered in the surrounding Río Orinoco and island habitats; and 3) Take samples as part of a programme monitoring avian viruses across the country. Logistics and scientific permits had been arranged accordingly. Caño Capuana and Río Orinoco My three days in Caracas before and after the Amazonas trip presented a perfect opportunity to visit old haunts, enjoy tropical pre-christmas meals with friends and former colleagues and pick up a few last-minute Venezuelan Christmas presents for Emma. I was hosted by David Mclachlan-Karr and together with Miguel Reabold we spent a day visiting Parque Nacional Guatopo, east of Caracas. An excellent morning s birding included White-necked Puffbirds, Collared Trogons, Venezuelan Parakeets, Golden-headed Manakins and wonderful views of an endangered Northern Spider Monkey (Mono Araña del Norte). 1

Once established in the urban Hotel Apure, José-Gustavo and I escaped for some late-afternoon birding in the dry chaparral landscape near Campamento Orinoquia ( La Garza ), 20 minutes drive south of the city. Highlights included Flame-crested Tanagers and three White-browed Purpletufts that had us confused for quite some time. Next morning we drove for one hour to the small and less than salubrious port of Samariapo, where we sweltered in the heat amidst the boats, dust and pre-christmas bustle as our gear was loaded onto the bongo (large dug-out canoe with shady roof) that would take us up the Río Orinoco some five hours to Capuana. On 2
the way upstream we caught our only glimpses of Bare-necked Fruitcrows, but generally things were quiet and the riverside forests much more heavily populated by local communities and degraded than e.g. Río Caura. A different kind of highlight for me was stopping off at the small riverside village of Puerto Nariño in Colombia, although as we headed further upstream we stayed closer to the Venezuelan side of the river avoiding any unnecessary risks! On arrival in Capuana we met the community s Capitán, set up camp, took a brief hike in the nearby forest, birded the savannah fringes and forest near to the river and strategised plans for the next day s activities. My highlights included several new flycatchers/tyrannulets, Ivory-billed Araçari and two species of Euphonia. Hot and tired I flopped into my hamaca, although sleep was not aided by the bats flying around in the roof! Black-chinned Antbird; White-flanked Antwren (imm.) Next morning whilst the others headed into Caño Capuana in search of the signs of the Orinoco Softtail, David, Jorge and I headed a couple of kilometres down river to a landing spot where we were able to scramble up the river bank and into the adjacent varzea forest. We then made our way through the forest, periodically projecting recordings of the softtail s calls and within 30 minutes we heard a response from tangled vegetation in a flooded area of forest. There followed a tense period whilst David called them in and we peered through the thick vegetation for glimpses. Eventually we had obtained good views and some photographs (first ever?) of three individuals and we were ecstatic! Subsequently I enjoyed watching the joint foraging habits of the softtails and a group of Black-chinned Antbirds. Orinoco Softtail (presumed immature and adult) Later in the day the rest of the team joined us to see the softtails and search for other territories in similar habitat. By the end of the day we had identified at least 14 individual softtails - not bad for a virtually 3
unknown species - both in the varzea forest along the main Río Orinoco and along Caño Capuana. In addition we had enjoyed sightings of Wire-tailed Manakins, Cobalt-winged Parakeets, Pygmy Antwren, White-flanked Antwren, Dusky Antbird, Yellow-bellied Dacnis and Rufous-bellied Euphonia. First in-situ photos of Orinoco Softtail (presumed immature and adult) We celebrated our success by swimming and doing laundry in the river, before a glorious sunset bade farewell to the day.

Our second full day was invested in further searches for softtail populations and taking digital recordings of the calls of various species encountered. In Caño Guacharaca we found more softtails, plus Channel-billed Toucans, Rusty-backed Spinetail, Amazonian Inezia and Drab Water-Tyrant. In Caño Grulla we again found more softtails, plus Black-tailed Trogons (very large and dramatic).

In the afternoon, with the Softtail mission accomplished, we found a gorgeous Tiny Hawk and some antshrikes with some apparently different characteristics from the northern forms of these species, plus a series of Rusty-backed Spinetail nests. Finally we spent the late-afternoon on a chain of sand islands in the middle of the Orinoco. There we found both Riverside Tyrant and River Tyrannulet, plus four different species of Nightjar and Nighthawk feeding over the river and island as the sun set. A night-time paddle with spotlights along Caño Capuana revealed a silent Great Potoo and a calling pair of Spectacled Owls.

After our third and final night in Capuana we spent our final morning en route to Samariapo doing an inventory of species on a series of Orinoco islands (personal highlights included Orange-headed Tanager and Chestnut-bellied Seedeater), then checking Caños Macúa and Merey for softtails (no response to playback, but good views of Yellow-throated Woodpecker and Long-billed Woodcreeper). We did, however, encounter a hectic mixed-flock in Caño Merey that included great views of a female Amazonian Black-Tyrant. In a nearby tree we found three amazing cicadas, complete with tail feathers. Amazonian Black-Tyrant (f) Unknown bird of prey (juvenile); Exotic Cicada After another night in Hotel Apure, Alejandro and José-Gustavo joined me for a few hours early morning birding along the well known Gavilán Road. We were quite disappointed to see the degree of deforestation (the air was full of the scent of fire), although we did see some nice birds including Crimson-crested Woodpecker, Bat Falcon, Golden-headed Manakin and Lesser Seed-Finch. 7
Lesser Seed-Finch (Gavilán Road); Frog (Capuana) Overall this was an amazing trip for me alongside such an expert team, made even more special by the successful completion of our goals - especially locating more of the Orinoco Softtails and generating lots of new data on their habits, habitat and range. In addition I saw some 149 species, of which 38 were new to me. Scenes at Capuana 8
